Translation of "Timing drive" in German

This timing drive connects the crankshaft to one or several camshafts.

This corresponds e.g. to a timing drive with two overhead camshafts.

In a compound slide, both axes are moved together by a motor with a timing-belt drive.

Gears or sprockets 72 which drive timing belts 73 are mounted on the journals 70.

A step-up or reduction gear 19 can be positioned between the motor 14 and the timing drive.

An upstream gear can be located between the timing belt drive and the electric motor 20.

Slide LRF can also be combined with a Timing-Belt Drive or chain drive to form automated solutions.

Timing belts on the advance: European automakers are increasingly turning to timing belts again instead of chains to drive timing gear.

Continental quality: The water pumps are now also available separately – for vehicles without a timing belt drive.

The GUF-P 2004 conveyor was equipped with a timing belt drive and balanced rollers.

The turnkey solutions combine a roller-bearing slide, the linear slide and a timing-belt drive in one integrated system.

The heavy-duty linear guide system PS 4-25 with timing-belt drive controls movement along the X axis.

The roller guide and high-performance timing-belt drive create the ideal conditions for high-speed operation.

By means of bearings 77, the journals 76, are also mounted in the center frame member 18 and carry sprockets 78 which drive timing belts 79.

The drive mechanism 12 of the connecting conveyor 2 has an electric motor, which acts by means of a gear 15, particularly a chain or belt drive, preferably a timing belt drive, with associated pinions or pulleys 16 and 17 on a driving shaft 18 driving the conveyor belt 10.

The drive mechanism 13 of the accumulating conveyor 3 also has an electric motor, which acts by means of a gear 21, particularly a chain or belt drive, preferably a timing belt drive with associated pinions or pulleys 22 and 23 (FIG. 5) on a driving shaft 24 driving the accumulating conveyor belts 7 and 8.

For this purpose the driving shafts 18 and 24 are interconnected by means of a timing belt drive 30 with associated pulleys 31 and 32 fixed to the driving shafts 18 and 24, accompanied by the interposing of a freewheel mechanism 29.

The freewheel mechanism 29 has a freewheel clutch 36 located in the timing belt drive 30, particularly in the pulley 32, which makes it possible for the driving shaft 18 to overtravel the driving shaft 24 when driven by the motor 14.

A driving shaft of the feed conveyor 1 can be gear-connected to the electric motor 14, particularly by a not shown timing belt drive and preferably accompanied by the interposing of an overtravellable, not shown freewheel mechanism.

From January 2012, the new linear guide with timing-belt drive will also be optionally available with a 25-mm ball rail or with two 15-mm rails.

It is therefore the object of the present invention to reduce the dynamic load in the power train, in particular in a timing chain drive, and to avoid the disadvantages of known solutions as well as to surpass their efficiency.

The invention relates to a chain wheel, in particular for a timing chain drive, comprising an axis of rotation, a sprocket arranged around the axis of rotation and having a plurality of circumferentially distributed alternating teeth and tooth gaps, and at least one chain guide, said sprocket and said chain guide being rigidly joined, said chain guide being provided with a circumferentially extending support contour for bearing on contact faces of link plates, and said support contour or raised portions thereof extending along a curved circumference which constitutes the perimeter of the chain guide.
